Application filed July 1, 1912.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, FREDERICK N. TAFF, a citizen of the United States,residing at Millington, in the county of Morris and State of New Jersey,have invented an Improvement in Cultivators, of which the following is aspecification.

My invention relatesto that class of agricultural machines designed forweeding purposes particularly in the vicinity of fragile vegetation andtrees.

The details of construction of my invention are hereinafter fullydescribed and'the novel features particularly pointed out.

In the accompanying drawing in which like reference characters denotecorresponding parts in the several views, Figure is a perspective viewshowing the machine in a working position. Fig. 2 is a plan view of thesame, and Fig. 3 is a side elevation, showing the machine with thecolters raised, in dotted or broken lines.

1 indicates an inclined standard, having its lower end resting upon ashoe 2, which shoe is secured at about its center to the standard bybolts or rivets 3 or in any suitable manner. This shoe 2 is madepreferably of a flat piece of metal with its ends upwardly inclined asshown. At the upper end of the standard 1 a drivers seat 1 is secured inany suitable manner.

5 is a gang bar preferably formed of angle iron and having its ends bentrearwardly a predetermined distance at an oblique angle. 6 is a crossbar also preferably made of angle iron and which is secured at each endto the rearward projections of the gang bar 5, by bolts or rivets 7, sothat it is in a parallel line with the forward or main body of the gangbar 5.

8 indicates spaced apart cultivator blades or colters the forwardportions of which are in a horizontal plane and are secured to both thegang bar 5 and cross bar 6 by bolts or rivets 9. These colters 8 at therear of the cross bar 6, are twisted into vertically inwardly inclinedpositions, so that the inclination of the blades on one side of themachine is opposite to that of the blades on the other side of themachine.

10, 10, are two hangers the upper ends of which are pivotally connectedto the standard 1 by a pivot pin or bolt 11. The lower ends of thesehangers 10 are spread apart and formed with hooks which pass throughspaced apart holes in the cross bar 6.

12, 12 are two runners, one at each side of the machine. These runnersare secured to both the gang bar 5 and cross bar 6 by means of angleiron 13 and bolts 14. The lower ends of these angle irons 13 are securedto the runners while their upright portions are provided with spacedholes for the bolts 14: and by which means they are verticallyadjustable upon the gang and cross bars.

15 is a vertical stud, the lower end of which is rigidly secured to thegang bar 5, at about the center thereof by rivets or in any suitablemanner. The upper end of the stud is formed as a sleeve 16 to receivethe pivot pin 17 of the-hand lever 18. The lever 18 is curved rearwardlyat its pivotal point and its lower end extends past this point for apredetermined distance and is provided with a hole to receive the hookedlower end of the rod 19. The upper end of this lever rod 19 is alsohooked and passes through a hole in the standard 1 forward of thehangers 10. The lever 18 swings closely adjacent the right hand side ofthe standard 1 and is provided on its inner surface with a lug orprojection 20 which is adapted to lock into the spaced notches orrecesses 21 on the side of the standard 1.

22 is a cross bar secured to the standard 1 adjacent its lower end andhaving its ends bent at right angles and provided with bolt holes.

28, 28 are two connecting rods between the cross bar 22 and the gang bar5. One end of each of these rods 23 is provided with an eye to receive abolt and they are thus pivotally connected at such end to the cross bar22, by bolts 241; the other ends of these rods 23, are hook shaped andpass through holes in lugs 25, upon the frontof the gang bar 5.

26, 26 are two metallic straps one end of each of which is pivotallyconnected with the cross bar 22 by the bolts 2-1, while their other endsare drawn together and receive between them the end of a draft rod 27which is provided with a bolt hole as are also the saidends of thestraps 26 which are secured together by a bolt 28, while at the sametime the said end of the draft rod 27 is pivotally secured between saidends of the straps 26 by said bolt 28. This draft rod 27 is looped atthe point projecting from between the ends of said straps 26, andextends back to the standard 1 as a straight rod where its end ispivotally connected to the standard 1 by a bolt 29. This looped end ofthe draft rod 27 provides means for connecting a whiflietree in theusual manner.

The depth of tilth may be regulated by the lever 18 which may be lockedin the desired positions by means of the lug 20 there on taking into thenotches 21 on the standard; and when desired the colters may be raisedclear of the ground by the same means, as shown in Fig. 3, in dotted orbroken lines. The bent and rearwardly extending ends of the gang bar 5form guard arms which prevent the colters from coming into contact withtrees and otherlike objects, and which in case the machine is driven toonear such object will warn the driver in time to prevent injury to thesame.

I claim as my invention:

1. A cultivator comprising a standard, a shoe attached to the lower endof the standard, a gang bar, a cross bar rigidly secured to said gangbar and jointedly connected with the standard, runners adjustablyconnected with the gang bar, spaced colters, one end of each of which issecured to said gang bar and said cross bar, and means for adjusting thecolters relatively to the ground.-

2. A cultivator comprising a standard, a shoe attached to the lower endof the standard, a gang bar having its ends bent rearwardly at an angleto form guard arms, a cross bar rigidly secured to said arms andjointedly connected with the standard, spaced colters, one end of eachof which is secured to said gang bar and said cross bar, and a handlever for adjusting the colters relatively to the ground.

3. A cultivator comprising a standard, a shoe attached to the lower endof the standard, a gang bar having its ends bent rearwardly at an angleto form guard arms, a cross bar, hangers forming jointed connectionsbetween said cross bar and said standard, spaced colters, one end ofeach of which is secured to said gang bar and said cross bar, and a handlever for adjusting the colters relatively to the ground.

4. A cultivator comprising a standard, a shoe attached to the lower endof the standard, a gang bar, a cross bar, ointedly con nected with thestandard, runners adjustably connected to the gang bar, spaced colters,one end of each of which is secured to said gang bar and said cross bar,and a hand lever for adjusting the colters relatively to the ground.

5. A cultivator comprising a standard, a shoe attached to the lower endof the standard, a gang bar, having its ends bent rearwardly at an angleto form guard arms, a cross bar secured at its respective ends to saidarms, jointed connections between said cross bar and the standard,runners adjustably connected to the gang bar and to said cross bar,spaced colters, one end of each of which is secured to said gang bar andto said cross bar, and a hand lever for adjusting the colters relativelyto the ground.
